I go running with DH when we can. Sweaty, red-faced and just..well, grim. he sees me in the morning...I have curly hair which has parties in hedges during the night. I am very sometimes a bit slapdash about bothering to take makeup off at bedtime.
But, saying that, after the run, after my morning shower, on a day to day basis I do put an effort in. A bit of an attempt to wear an "outfit" rather than slobby jeans and t-shirt. That may mean it is just all clean and I have a necklace or cardigan on. Or I may preen and primp a bit more - a nice top/jumper rather than t-shirt and cardigan. But no longer working in an office so does tend to be casual wear.
I 99.9% of the time wear make-up though. I feel naked/uncomfortable without it. Just a bit of eye-liner, mascara, blusher. I do style my hair (as much as I can with the curls). I feel relaxed groomed.
So that is my look for a lot of the time (unless, as above, running or just awake or maybe gardening).
But I do my casual grooming for me. It is what I did when single. I feel happier if I have put in a bit of effort. My DH could not give a monkies. He possibly prefers it. I have no idea. He thinks I am amazing whatever I look like. He is the only person I feel comfortable with being bare-faces and wild-woman haired.
If you are doing it for him - question it. If your want to look "presentable" for yourself then that, imho if absolutely, totally fine.
I do not think you deserved the laughter and mocking.
